When I create a new account and send the new Welcome email, the email contains the password I set.
When I update the password for an existing account, click the require password re-set box, and send the Welcome email, the email contains the temporary password I set.
When I update the password for an existing account, DO NOT click the require password re-set box, and send the Welcome email, the email DOES NOT contain the password I set.
It would be useful to populate the new password for this last use case as well.
